Before you install
- Requires network device access with valid credentials; device must support one of NAPALM's supported operating systems and may require specific feature enablement (e.g., XML agent on IOS-XR, NXAPI on NXOS).
- Low install friction with a pure-Python wheel.
- Active maintenance with a release 18 days ago and 2486 GitHub stars.

What it is and what it does
NAPALM is a Python library that abstracts network device vendor differences behind a single API, letting you write automation code once and run it against multiple supported platforms. It handles the low-level details of connecting via SSH, NETCONF, or vendor APIs, and provides methods to retrieve device facts, configuration data, and operational state, as well as to push configuration changes.
The library is designed for network engineers and automation platforms (Ansible, SaltStack, StackStorm) that need to manage heterogeneous networks without rewriting logic for each vendor. It depends on vendor-specific libraries like netmiko, junos-eznc, and ncclient to handle device communication, and uses textfsm and jinja2 for parsing and templating. Device-specific caveats and feature requirements are documented, and the library provides a CLI tool for testing connectivity and basic operations.
Use it for
- Retrieve operational data (facts, interfaces, routes) from multiple vendor devices in a single script.
- Push configuration changes to routers from different vendors using a unified method call.
- Integrate network device management into Ansible playbooks or SaltStack states without vendor-specific modules.
- Validate network device configurations by comparing running and intended state across a fleet.
- Build custom network automation tools that work across multiple supported network operating systems.
